Bulisina Co.  is pleased to offer a range of proven products for scale control in membrane applications. These customized products—the BCT® RO product line – are designed to provide outstanding performance for severe service and general purpose applications.

Reverse Osmosis Membrane Cleaners

The key to maintaining good performance is to clean as soon as possible
after performance begins to decline. Initial fouling of a membrane surface
will change the flow within the system and encourage further and more
complex fouling to occur.

Reverse Osmosis Membrane Antiscalants

The use of high performance RO membrane scale inhibitors is an essential component of any good reverse osmosis plant management programme. Reverse Osmosis Chemicals International offer a range of advanced technology RO scale inhibitors developed to deliver superior scale prevention performance, product stability across a wide pH range and excellent membrane compatability. Scaling of RO membranes may occur when sparingly soluble salts are concentrated within the element beyond their solubility limit. For example, if a reverse osmosis plant is operated at 50% recovery, the concentration in the concentrate stream will be almost double the concentration in the feed stream. To minimize precipitation and scaling, it is important to establish well-designed scale control measures and avoid exceeding the solubility limits of sparingly soluble salts. In an RO/NF system, the most common sparingly soluble salts encountered are CaSO4, CaCO3, and silica. Other salts creating a potential scaling problem are CaF2, BaSO4, SrSO4, and Ca3(PO4)2.

RO Biocides

Our range of high performance biocides are suitable for use in reverse osmosis systems. Non-oxidizing, non-ionic biocides can be used either on line or as part of a cleaning program to control biofouling in reverse osmosis membranes. When used as an on-line treatment, ROC biocides should be dosed prior to the RO system to control bio-growth in the membranes.
